similar to: AMR vs Speex on wireless networks.

NB for CSD/HSCSD and WB for UMTS/HSDPA. The UMTS/HSDPA services already provides an excellent turbo code correction. For what i know i can tell you more about corrupted packets. The BER ranges from 10^-5 to 10^-2 for CSD/HSCDS in transparent mode, and from 10^-9 to 10^-6 for UMTS/HSDPA. It depends on signal quality and if you're walking/standing or if you're in real mobility (for example

In order to develop a Voip application, today i should make it robust to bit-errors over wireless networks. This is an actually lack of Speex, infact what i've understood is that if a packet arrives corrupted, i must pass NULL to the decoder in order to let it know. My target is to use UDP (with checksum field disabled) and exploit also corrupted packets giving them to the AMR codec. Otherwise

Can i use a separate instance of the decoder passing NULL to generate white noise or something that is similar to confort noise? I need to feed it to my output audio autput device for each frame i don't receive in time. Or should i just use the same decoder instance of voice and just pass NULL when i discard or loss frames? Is that the best way? How can i accomplish this purpose? Thanks.

You need to let the know packets are missing so it can generate something meaningful instead. Otherwise, you'll also have less packets to play, which means "something" has to be inserted (zeros, clicks, the content of the kernel memory, ...) instead. As for crashing, it shouldn't happen and I wouldn't be surprised if it had more to do with a soundcard underrun occuring from

I would like to know if my vision of things is correct about frame structure. -------------------------------------------------------- Frame header -------------------------------------------------------- Subframe1 header|Subframe1 content| -------------------------------------------------------- Subframe2 header|Subframe2 content| --------------------------------------------------------

Hi Srs., Do you know if it's possible make a videocall from asterisk to UMTS mobile phone?. Both technologies use H.263 like videocodec. Any idea? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20050930/ea37cdf9/attachment.htm

Dear R-help list, I'd like to create visualize the clustering of a dataset with a dendrogram. I'm using the following script: data = read.table("data.csv", header=T, sep=";") require(cluster) res = as.dendrogram(agnes(data)) chlab <- function(n) { if(is.leaf(n)) { att <- attributes(n) labx <- data$category1[att$label] lab_color <- ifelse(labx ==

Hi, i'm new to the list, this is my first post here. I have a UMTS module that can be used like a modem and associated with a SIM card (on a simple board) can make phone and data call towards a real phone. Basically is a sort of rough phone that i configure and use by AT commands. It can handle and receive incoming call to the phone number associated to the sim very easily. I connect the

Hi, we have a DSL outage in our office, which will last for one week. So I have to use an usb umts stick, can someone recommend a stick / provider for germany? Maybe which works out of the box? I know O2 has explicit Linux support but only Fedora 16 and up.... Thx Rainer

Hello, I am searching for an internet usb surf-stick (umts) that works under CentOS. Is anyone using such a stick and if so, which chip has this usb-stick? Would a Huawei E160E chip work under CentOS? Or maybe under CentOS with the 2.6.35 kernel from elrepo? Thank you very much! regards Olaf

Hello, I'm remotely managing an asterisk setup using an OpenVPN client on this Asterisk box, connecting to an OpenVPN server of mine). This box is mainly connected to PSTN. It is also connected to the Internet, only for remote management. The former ADSL link has recently been replaced by a new 4G link (UMTS). I'm connecting to this box from a Debian Jessie/Gnome Terminal combo. With

Hi Tom, thanks and congrats for LLVM 10.0.1-rc1 release. [1] shows 2 assets. 10.0.0 RCs had a lot of more assets. I am missing the llvm-project-10.0.1rc1.tar.xz tarball. Will you provide them later or is there a new development/workflow decision I do not know of? BTW, the source zip and tar.gz tarballs show no sizes. I am using Mobile LTE/UMTS to download stuff from the Internet. For now I

hi, i'm used to manual partition and format disks before installing the O.S. but with centos 5 this results in an unbootable system. Usually, to manual partition the disks I use the installation disk in recovery mode.. The partition schema I choose was: /dev/sda1 /boot /dev/sda2 swap /dev/sda3 LVM PV inside the LVM VG I created the following LV / /var /home /tmp Then I formatted all

Hi! I want use in my file swf actionscript coomand "loadmovie" but I didn't see it into swfdec-0.5.2. I saw that tehre is a fuction (swfdec_movie_load) that permit to load a movie (second file swf flash) into a current swf file So...How can I do to call this fuction? while actionscript command should to be call by my swf file?
